Use this parameter to set the inductance saturation point.
1-49 Current at Min Inductance for q-axis
Default value:
100%
Setup:
All setups
Data type:
Uint16
This parameter specifies the saturation curve of the q-inductance values. From 20–100% of this parameter, the inductance is linearly
approximated due to parameter 1-38 q-axis Inductance (Lq) and parameter 1-45 q-axis Inductance Sat. (LqSat). These parameters are
related to the motor nameplate load compensations, the application load type, and the electronic brake function for quick stop/hold of
the motor.

Parameters for load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Default value:
100%
Setup:
All setups
Data type:
Uint16
Use this parameter along with parameter 1-52 Min Speed Normal Magnetising [Hz] to obtain a different thermal load on the motor when
running at low speed. Enter a value that is a percentage of the rated magnetizing current. If the setting is too low, the torque on the
motor shaft may be reduced.
